LED - A type of lighting technology that uses semiconductor devices to generate light. LED lights are more energy-efficient and have a longer lifespan than traditional incandescent bulbs.

CRI - A measure of a light source's ability to render colors accurately. The higher the CRI, the better the light source is at rendering colors.

CCT - A measure of the color temperature of a light source. The higher the CRI, the cooler the light source is.

Wattage - A measure of the power consumption of a light source. The higher the wattage, the more power the light source consumes.

Voltage - The measure of the force that drives an electric current.

Downlight power

The power consumption of a downlight is measured in watts (W). The more watts a downlight uses, the more power it consumes. The power consumption of a downlight is affected by the type of light bulb used, the number of bulbs used, and the voltage of the electrical system.

The light output of a downlight is measured in lumens (lm). The more lumens a downlight produces, the brighter it is. The light output of a downlight is affected by the type of light bulb used, the number of bulbs used, the wattage of the light bulbs used, and the reflectivity of the surfaces around the downlight.

LED Downlight Output

Common downlights lumen ranges

The amount of light output required from a downlight depends on the purpose for which the downlight will be used.

300-700 Lumens - are great for general lighting in a room.

800-1200 Lumens - are better for task lighting, such as in a kitchen or bathroom.

1200-1600 Lumens - can be used for accent lighting, such as highlighting artwork or architecture.

1700 Lumens and up - are best for outdoor use, such as in a porch or garage.

The common color temperature of downlights

The color temperature of a light source is measured in Kelvin (K). The higher the Kelvin, the cooler the light source is.

2700K - is a warm white color temperature, and is often used in living rooms and bedrooms.

3000K - is a cool white color temperature, and is often used in kitchens and bathrooms.

4000K - is a daylight color temperature, and is often used in offices and task-oriented rooms.

5000K and up - is a super daylight or blueish color temperature, and is often used in outdoor lighting.
